Find the value of the given function's derivative at x=3
Rasek [7]
<h2>Explanation:</h2>

According to the chain rule, if we have a function:

f(x)=k(g(x))

The derivative at a point a will be:

f'(a)=k'(g(a))g'(a)

We know that:

f'(3)=k'(g(3))g'(3)\\ \\ \\ a=3 \\ \\ \\ Then: \\ \\ g(3)=2(3)-3^2 \\ \\ g(3)=6-9 \\ \\ g(3)=-3 \\ \\ \\ k'(g(3))=k'(-3)=2 \\ \\ \\ g'(x)=2-2x \\ \\ g'(3)=2-2(3)=-4 \\ \\ \\ Finally: \\ \\ f'(3)=2(-4) \\ \\ \boxed{f'(3)=-8}

Nutka1998 [239]

Answer:

Step-by-step explanation:

31) Y = -3x² + 18 x -25 = -3*x² + -3*-6x -25

  = -3(x² -6x) - 25

( (a-b)² =a² - 2ab + b²;   here a = x; 2ab = -6x = -2*x*3; and so b = 3)

  = -3(x² -6x + 9 - 9) - 25  

 { when we add and subtract 9, the equation will not change}

= -3[(x -3)² - 9] -25

= -3(x - 3)² - (-3)*9 - 25

= -3(x - 3)² + 27 -25

= -3(x - 3)² + 2

32) y= -3x² - 18x - 25

    = -3 (x² + 6x )-25

  = -3 (x² + 6x + 9 - 9) -25

= -3 [ (x+ 3)² - 9] -25

=-3 (x + 3)² - (-3)*9 - 25

= -3(x + 3)² + 27 - 25

= -3(x+3)² +2
